The closest thing to the sky in nature
Hakone-en Aquarium

Hakone-en Aquarium, located 723 meters above sea level on the shores of Lake Ashi, is Japan's highest aquarium. The Seawater Hall, a 7-meter-tall outdoor aquarium, is particularly notable. Hakone-en Aquarium boasts 450 species and 32,000 fish from around the world. Stepping outside the aquarium building, you can admire the majestic Mount Fuji and the beautiful Lake Ashi from this elevated vantage point.

Baikal Seal Plaza

Baikal seals are rare freshwater seals found only in Lake Baikal, Siberia, Russia. These seals can be seen in very few places in Japan, and Hakone-en Aquarium is a prime example. Their large, round eyes and adorable appearance make them a popular photo spot. Furthermore, visitors can even feed the seals themselves (for a fee), making this a popular attraction every year. Come see the Baikal seals, the "icon" of Hakone-en Aquarium, up close.
